TO ALL WHGM IT MAY CONOERN:

Be it known that I, D. H.,HEYEN, of the city, county, and State ofl New York, have invented a new 'and usei'ul Improvement in.Lii`e-Preser\f'ers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to Ineke and use the same, reference being had to the accompanying drawings, forming part of this specification.

This .invention relates to a new and improved method of constructing life-preservers, whereby they are made-muo'lrmcre effectual in case oi' need, and much less liable to injury from accident; and the invention consists in combining an elastic air-tight tube with a broad substantial belt, thereby eftectually protecting the airtube from injury, 4and rendering its application to the purpose intended much more easy than where air-tubes f or vessels are attached directly to the body as .life-preservers without such support. m Figure 1 represents the life-preserver complete land ready to be attached to the body.

Figure 2 is a yview ofthe same when so att-ached.'

`Similar letters of reference indicate corresponding parts.

A represents a belt of cloth or of some other light and substantial material, arranged with buckles and straps for securing the samearound the body, as= seen in the drawing. B represents an air-tight elastic tube, formed of rubber or of some other suitable material',` and attached to the belt in sinuous or serpentine form by A-clips mark-ed O, as seen in the drawing., These clips are elastic, so that they expand with the air-tube when the tube is filled with air. When not filled, the tube and the clips will lie fiat upon the belt, so that the belt inny be 'worn under the clothes around the body, and be inated as occasion may require. Upon the outer end of the tube there is a mouth-piece and valve, through which the air is introduced, and by which it is conlined when the tube is inflated.

In applying the life-preserver, it is buckled around the body, with the air-tube on'the outside, as seen in the drawing, where it may be worn (as before stated) when on the water, as an/ever-reafly safeguard in euse of accident or danger.

Having thus described my invention, what I claimas new, and desire to secure by Letters Patent, is- The air-tube B, in combination with the belt A., attachedA and arrangedsubstantially as shown and described for the purpose set 'fot-th.

The above specification ot'I my invention signed by me, this 21st day ot'June, 1867.

D. H. HEYEN.
